articulatedcar to its support.

A further object of the invention being the provision of means to maintain a vestibule member of an articulated car in proper position with relation to the adjacent bodies, Whenever said car is traversing curves or uneven portions of railroad track;

These and further objects will be apparent from the following description.

Fig. 1 is a plan view of the vestibule member showing its relation to the adjacent ends of two adjacent bodies and -the truck commonto both bodies, when the cars are in a straight line; Fig. 2 is a plan View of the same bodies and shows the relation of the vestibule member to them while they are rounding a curve; Fig. 3 is a sectional view taken along the lines AA on Fig. 1 and shows the vestibule member in conjunction with its anchorage; Fig. 4 is a sectional view taken along the lines AA of Fig. 1 and shows the action of the anchor rods when the vestibule member is tilted as with the rocking of the car bodies or the turning of the vestibule member when'rounding a curve; Fig. 5 is an enlarged detail of oneof the anchor members.

As shown by the drawings the invention is embodied with a vestibule supported on one of the adjacent ends of two adjacent bodies. It is to be understood, however, that I do not desire to limit myself to this 7 specific mode of supporting the vestibule member for it can be supported equally as well on the truck or any other suitable bearing. v

Referring now in detail to the drawings the reference character 1 indicates a vestibule member, of the preferred cylindrical form, with a passageway 2 formed therein. At the base of the vestibule is shown the bearing member 3 supported in its base 4:.

' This base member t is better shown in Figs.

1 and 2 and in the present form is fastened tot-he underframe 5 of one of the bodies and extends between the two bodies above their common truck. The underframe 5 referred to is supported, with the adjacent end of the other member of the articulated car, in a bearing 6 which'may be of any suitable form and carried by a truck, the bolster 7 of which is shown in the drawings.

anchor-rods 8 are attachedat the side of the vestibule memberi'lby suitably arranged brackets 9. At the other ends of therods 8 are shownibrackets 1O cooperating with eyes 11 on the .rods to; fasten .them to the truck bolster 7.- 1

When the vestibule member is normal to the truck the rods serve the purpose of keeping the vestibule member in an upright position and prevent any undue vertical displacement. While the cars are traversing a curve the vestibule is turned relative to the bodies so as toform at all times a continuous passageway between the two adjacent bodies, this position being shown in Fig.

2. As will be seen from the drawings this horizontal movement of the vestibule member without any corresponding vertical displacement requires a lengthening of the anchor rods. This compensating movement is taken care of by the washers 12 and 13 with the spring 14: as shown in detail in Fig. 5. The upper washer 12 is fastened to the rod 8, but the lower Washer 13 is free to move on the rod. The spring 14 bearing in cups 15 of the washers serves to separate them and keepsa tension at all times between the washers to maintain the rod 8 at a proper The bracket 9 is provided with a portion which is slightly curved at the point where the rod 8 passes through it and corresponds to the contour of the contacting washer 13 to allow the rod 8 to tilt with any movement of the vestibule.

During any swaying of the car bodies and corresponding movement of the vestibule, the spring 14 in conjunction with the washers 12 and 13 allows freedom of movementbetween the brackets 9 and the rods 8, thus it will be seen that while the vestibule is at all times positively connected to the underframes or trucks, by the anchor members, there is also freedom of movement provided between these anchors and the vestibule member. 1

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. In an articulated car, adjacent ends of two adjacent bodies supported on a common "truck, a vestibule member, spanning 'the lOO llO

to maintain said vestibule in its bearing during operation of said articulated car.

2. 111 an articulated. car, adjacent ends of two adjacent bodies supported on a common truck, a vestibule member between said bodies and supported in a pivot bearing secured only to one car body, anehor rods on said vestibule to maintain said vestibule in connected relation With the bodies and truck at all times, said anchor rods being flexibly connected at both ends thereof.

3. in an articulated car, adjacent ends of two adjacent bodies supported on a common truck, a vestibule member spanning the space between the bodies and supported in a suitable bearing, anchor rods on either side of said vestibule member connected to the truck, said rods having eonipeinaiiti11g means at one end and rotatably connected at the other end to hold said vestibule member in place during the operation of the car.

l. 111 an articulated car, adjacent ends of two adjacent bodies resting on a common truck, a vestibule member, between said bodies anchor rods at each side thereof, eyes on one end of each of said rods and a spring controlled sliding connection at the other ends thereof, to adjusting said rods to tilting or twisting movements of said vestibule member when the car is in motion.
